ABSTRACT
AR and virtual reality (VR) technologies are like a double-edged sword: displays can be compelling and powerful, yet when certain design principles are violated, they can be confusing and unusable. Chapter 5 explores some of the reasons for ambiguity and unusability from the perspective of human–computer interaction, which necessitates a design process that is informed by basic scientific results from the overlapping domains of perception, action, and cognition. The chapter examines some of these fundamental concerns for general AR, then focuses on the implications for particular applications in surgical planning, guidance, and targeting, with some specific case studies drawn from published papers on the use of AR for neurosurgery.
